The Clássico is indicated for those who appreciate a pure and crystalline sound in their instrument with nylon string. Coated with Bronze 65/35, the Giannini Clássico GENWXPA is the best for those who like strings with a super extra heavy tension.

All Giannini strings are produced in Brazil, at our factory in Salto, in São Paulo.

Differences between Clássico x Titanium series

The difference between the Classic and Titanium series is basically in the materials used (the monofilament plain treble strings, and the Bronze-coated low strings), which affect the sound in each series:

Cristal Nylon (Clássico series) - Treble strings (strings 1, 2 and 3)

Medium tenacity nylon monofilament, closely associated with the classic sound of the nylon guitar. It produces a sound with balanced brightness, great definition and good sustain. Appreciated for recordings thanks to its tonal stability and tone balance.

In both the Classic and Titanium series, the low strings (strings 4, 5 and 6) are silver, with nylon filament (internal) and visually similar.

In the Classic Series, covering the nylon filament we have Bronze 65/35 (alloy of 65% Copper and 35% Zinc and a small layer of Silver), which produces a sound with a highlighted shine (much appreciated by musicians who use the strumming style, but with a softer grip than the 85/15 Bronze found in the Titanium Series.

We can say that for the Clássico strings we have a balanced tone, with great definition and good sustain, which would correspond to the expectations of those who want a more “traditional” sound from a classical guitar.

ISO 9001 Quality Seal

The entire line of Giannini strings has the approval of the ISO 9001quality seal. But what is the ISO 9001 seal?

ISO 9001 is a series of norms and rules that seek to guarantee the final quality of your strings. These procedures range from the choice of the raw material and its suppliers, going through the entire production process of the strings, training of the labor involved in the production, its distribution, until the product reaches the dealers and the consumer. These processes and all those involved in it undergo audits every year, to verify that they are being followed according to the established standard, so that the seal is renewed.

Since 2007, Giannini has been awarded the ISO 9001 seal in its strings line, which is renewed annually, proving the quality of each string that you use in your instrument.
